The best way to bulk convert images to PDF file on Windows 10?

Using Libre Office as an image to PDF converter on a Windows PC is a completely free, open-source method. You have two main approaches within Libre Office, depending on whether you want to convert a single image or combine multiple images into one PDF.

Method 1: Using Libre Office Draw as Image to PDF Converter

Libre Office Draw is the vector graphics application within the suite. It is ideal for this task because it can directly import images and export them as PDFs.

1. Open Libre Office Draw: Launch Draw from the Libre Office start screen.

2. Insert Your Images: Go to Insert > Image > From File on the menu bar . Navigate to your images and select them. You can insert multiple images at once. Alternatively, you can simply drag and drop image files directly into the Draw window.

3. Arrange the Images: If you inserted multiple images, they will appear stacked on top of each other. You can drag them to reposition them on separate pages, or arrange them on a single page as needed. To add a new page, go to Insert > Slide or Insert > Page.

4. Export as PDF: Once your images are arranged, go to File > Export As > Export as PDF.

Method 2: Using Libre Office Writer as Image to PDF Converter

1. Open Libre Office Writer: Launch a new Writer document.

2. Insert Your Images: Click in the document where you want the first image to appear. Go to Insert > Image > From File and select your first image. Repeat for additional images, pressing Enter to add them on new lines or new pages.

3. Arrange and Edit: Click on each image to resize it or drag it to a new position. You can also add captions, text, or page breaks between images.

4. Export as PDF: Go to File > Export As > Export as PDF.

5. Adjust Settings and Export: As with Draw, you can adjust compression and resolution settings. Click Export to save your document as a PDF.
